TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 272,028, dated February13,1883. 7

Application filed March 22. 1882. (ModeL) Massachusetts, have inventedcertain new and useful Improvements in Temporary Binders; and I dohereby declare that the following is a full, clear, and exactdescription of the same,

reference being had to the annexed drawings, making apart of thisspecification, and to the letters and figures of reference markedthereon.

Figure l of the drawings is a perspective view of my invention. Fig. 2is an under plan view; and Fig. 3 is a section of the same, takenthrough the line at m, Fig. 2.

This invention relates to devices for temporarily filing or bindingbills, letters, or other similar papers which are wanted for readyreference, and in which one or more such papers may be readily removedwhen needed without disengaging the others that may be on file.

The invention refers more particularly to that class of devices in whichtwo stationary ing, in connection with two curved swinging wires, tohold and retain the letters, bills, or other papers, the swinging wiresbeing connected bya cross-bar and held in the position placed by aspring bearing on said bar, the swinging wires working through elongatedopenings formed in the base-plate.

It is the object of the invention to improve the construction of theabove-mentioned class of binders; and it consists in the details ofconstruction substantially as shown in the drawings, and hereinafterdescribed and claimed.

In the accompanying drawings, A represents a flat base-plate, cast withan eye at its top for the purpose of hanging the same against a wall ordesk, if so'desired, and with a rim, a, around its edges. This plateis'also provided with slots b, through which work lugs 0, cast with alever-bar, B, which is formed with a beveled shoulder, g, to act againstthe fulcrums h on the under side of the base-plate, said lever-barworking above and controlled by a spring or springs, (l, secured by ascrew and washer to projections d, this lever being prevented fromslipping by a stop, 0.

The requisite amount of tension is given to the springs (J by means of across-plate, D,

which is caused to bear upon said springs with a greater or less degreeby a suitable screw passing through it and the base-plate.

Suitably connected to the lugs c of the lever-bar B are wires E, theupper ends of which are curved or arched and brought to a point toengage with the beveled ends of the tubular upright standards F,connected to the baseplate for the purpose of receiving the papersintended to be filed. These standards are made tubular, in order that acord may be passed through them, with which to secure the file of paperswhen removed from the binder.

When a paper is desired to be placed on file the curved wires connectedto the lugs upon the lever bar, as heretofore described, are swung backand the said paper placed upon the upright tubular standards, when thecurved wires are brought back,'their points engaging with the beveledends of the standards, thereby preventing the paper from becomingdisengaged or working 05.

.When a paper on file is needed for reference those placed upon thestandards subsequently to the one desired are pushed up on the curvedswinging wires, and the whole swung back out of the way to allow of itsremoval, the pressure of the springs upon the angular corner of thelever-bar holding the swinging wires firmly in this position untilbrought back against the beveled standards.

Having now fully described myinvention,

what I claim as new, and desire to secure by Letters Patent, is-

In a temporary binder, the base-plate A,

cast with rim a, openings b, and fulcrums h p and stop 0, said basehaving secured thereto the standards F, in combination with the wires E,connected to lugs c, the lever-bar B,formed with bevel-shoulder g, thesprings C, and adjusting cross-bar I), all constructed and arranged tooperate substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence two witnesses.

AUGUSTUS S. BUNKER.
